Yes, manufacturers still produce magnesium wheels, but only for niche, high-performance applications such as motorsports, racing, and select military vehicles 🔧. If you're asking how to choose magnesium wheels, it's crucial to understand they are no longer common in consumer automotive markets due to cost, corrosion sensitivity, and availability of advanced aluminum alloys. For most drivers, forged aluminum wheels offer better value and durability. However, if you need the absolute lightest unsprung weight for track performance, magnesium remains unmatched. When evaluating options, focus on alloy composition (AZ80 vs ZK60), certified load ratings, proper surface coatings, and verify compatibility with your vehicle’s hub and braking system. Avoid used or uncertified magnesium wheels—these can pose serious safety risks.
❗ Key Decision Tip: Only consider magnesium wheels if you’re in motorsports or restoring a classic race car. For daily driving or even spirited road use, modern forged aluminum wheels are safer, more durable, and easier to maintain.
About Magnesium Wheels: Are They Still Made?
Magnesium wheels are lightweight alloy wheels made primarily from magnesium, often blended with aluminum and zinc to improve strength and ductility. Historically popular in 1960s–1980s racing, they offered a significant weight advantage over steel and early aluminum wheels 🏎️. The key appeal lies in their exceptional strength-to-weight ratio—magnesium is about 33% lighter than aluminum and 75% lighter than steel at equivalent strength levels.
So, do they still make magnesium wheels? Yes, but in very limited quantities. Production continues mainly for Formula 1, endurance racing (like Le Mans), vintage race car restorations, and some aerospace or defense applications. Companies like BBS, ATS, and Ronal still offer magnesium wheels under special order or through OEM racing divisions 1. These are not sold through typical retail channels and require expert installation and ongoing maintenance.
Why Magnesium Wheels Are Gaining Niche Popularity Again
While magnesium wheels never disappeared entirely, recent interest has resurged among collectors and motorsport enthusiasts restoring classic race cars from the 1970s and 1980s 📈. Lightweighting remains a top priority in performance engineering, and magnesium delivers where every ounce matters. Additionally, advancements in protective coatings—such as anodizing, chromate conversion, and ceramic sealing—have improved corrosion resistance, making them slightly more viable in controlled environments.
The motivation behind choosing magnesium today isn’t mass-market appeal but rather authenticity in restoration projects or pursuit of marginal gains in competitive racing. Enthusiasts seeking period-correct builds for events like Historic Grand Prix races often source magnesium wheels to maintain originality and reduce rotational mass.
Types and Variants of Magnesium Wheels
Magnesium wheels come in two primary manufacturing types: forged and cast. Each has distinct characteristics affecting performance, cost, and longevity.
1. Forged Magnesium Wheels ⚙️
- Pros: Highest strength-to-weight ratio, excellent fatigue resistance, ideal for high-stress racing environments.
- Cons: Extremely expensive ($3,000+ per wheel), long lead times, limited availability.
- Best for: Professional motorsports, prototype testing, high-end restorations.
2. Cast Magnesium Wheels 🏭
- Pros: Lower cost than forged (though still high), allows complex designs, historically accurate for vintage models.
- Cons: More brittle, prone to cracking under impact, lower fatigue life.
- Best for: Display vehicles, low-mileage historic replicas, non-competitive track days.
Common Alloy Types
- AZ80: High aluminum content; good castability and moderate strength. Common in older wheels.
- ZK60: Zinc and zirconium enhanced; higher strength and creep resistance. Used in modern forged applications.
Key Features and Specifications to Evaluate
When researching how to choose magnesium wheels, focus on these technical and practical factors:
- Alloy Composition: Verify whether it’s AZ80, ZK60, or another variant. ZK60 offers better performance under stress.
- Weight: Typically 20–40% lighter than equivalent aluminum wheels. Confirm exact specs from manufacturer data.
- Load Rating: Must match or exceed your vehicle’s requirements. Look for certified test reports.
- Finish & Coating: Anodized, painted, or sealed surfaces help resist corrosion. Uncoated magnesium degrades rapidly.
